APT: Fixing 1386 Warning

When running apt update on Ubuntu, you might encounter a warning like this:

N: Skipping acquire of configured file 'main/binary-i386/Packages' as repository 'https://brave-browser-apt-release.s3.brave.com stable InRelease' doesn't support architecture 'i386'

This error occurs because the system attempts to fetch all architectures, including i386, while your Ubuntu installation is amd64.

The solution is straightforward. In this case, the source list for the Brave browser is located at /etc/apt/sources.list.d/brave-browser-release.list.

You need to specify the archictecture using [arch=amd64].

Change the line:

deb [signed-by=/usr/share/keyrings/brave-browser-archive-keyring.gpg] https://brave-browser-apt-release.s3.brave.com/ stable main

to:

deb [arch=amd64 signed-by=/usr/share/keyrings/brave-browser-archive-keyring.gpg] https://brave-browser-apt-release.s3.brave.com/ stable main

Finally, run apt update again, and the warning should be resolved.
